Brief summary

Third molar surgery is the most frequent procedure in oral and maxillofacial surgery. Surgical wound infection is the most prevalent complication. Determine if the use of 2 gr. of Amoxicillin as AP reduces the proportion of postoperative infectious complications in the impacted third molar extraction compared to placebo. To determine the proportion of postoperative infectious complications of the experimental group (2 gr Amoxicillin) and control group (placebo) derived from the exodoncia of impacted mandibular third molars. To compare the proportion of postoperative infectious complications of the experimental group versus the control group. To compare the proportion of rescue medication requirement associated with postoperative pain between the experimental group versus the control group. Describe any adverse reactions resulting from the use of 2 gr. Amoxicillin as AP.

Interventions

2 gr. Amoxicillin one hour before the surgery . Oral tablet
